After the early application of nitrogen peanuts into the seedling stage, the nitrogen in the seeds is basically used up. At this time, the nitrogen fixation capacity of the root phylloxera on the seedling roots is very weak, and the quick-acting nitrogen fertilizer is added early, which is not only beneficial for cultivating strong seedlings, but also promoting early flower bud differentiation. But also play a role in promoting the development of rhizobia. In general, 3000 kg of high-quality rotten farmyard fertilizer and 5 kg of urea are used as base fertilizer per acre. The time for applying seedling fertilizer can not be later than the flowering needle period, and should not be too much. After the first time, the topdressing fertilizer was applied to harvest the top peanuts immediately before the harvest. The amount of fertilizer used was 30-40 kg of peanut fertilizer per acre, or 10 kg of urea, 15 kg of diamine, and 10 kg of potassium chloride. The second top-dressing in the young fruit began to swell, generally topdressing 10 kg of urea per acre. Full application of phosphorus and phosphate fertilizer in the growth process of peanuts, not only can effectively enhance the nitrogen-fixing ability of rhizobia, but also can significantly promote the reproductive growth of plants, and can improve the quality of peanuts. The peak period of phosphorus requirement for peanuts is mainly before the sowing period. Therefore, sufficient phosphorus fertilizer should be applied in the early stage. It is advisable to apply 12 kg of calcium phosphate per acre. After ridge sealing, if there is insufficient phosphate fertilizer, 3% of superphosphate solution can be sprayed, sprayed once every 7-10 days, and sprayed 2-3 times. Qiao calcium supplement peanut is a kind of crop that likes calcium especially, the calcium fertilizer takes gypsum as good, the dosage per acre is about 20 kilograms. The gypsum was ground into a fine powder when applied, and applied during the flowering period of peanuts and when most fruit needles were introduced into the ground. If the peanut tree grows too vigorously, you can use the feet to step on the peanuts. This will not only prevent the seedlings from prospering, but also help the fruit needles.
